[jboss-user] [EJB/JBoss] - Ignoring empty contained entities

I have a question regarding the possibility to ignore entities dynamically, based on whether or not they contain data. Let me explain: 

class Person implements Serializable {
  private Information info = new Information(); 
  private String name;


now I don't want to save the information in case it remains empty, but at the same time I want to make use of the cascading functionality, but at times, Persons don't have information the information object would be empty. I cannot just leave it out, since I work with Seam and info.description for example might be injected, but if that field for example is null, I would like to ignore the info object so that I don't have any null-containing rows in the database. Also the not-null annotation does not help me...

Any ideas?
